In the article it called it a backdoor pilot. They didn't say what that meant but I took it to mean it was kind of a wait and see what the ratings are for the pilot. That's my best guess.

I'm not surprised about the ratings. Not just for the quality of the show, but I only just stumbled upon it last night when I was looking to see if there was anything on to watch. I remember reading an article about it in TV Guide when the information about new shows for this recent season were coming out. That was of course late last year so I completely forgot about it.
